Trivia: When Al asks Marcy why the show "No Pot to Pease In" was cancelled, she responds that a woman in Michigan didn't like it. In Bloomfield Hills, Michigan, a woman named Terry Rakolta started a boycott after watching the episode "Her Cups Runneth Over." The intent was to get Married...With Children taken off the air. Her boycott had the reverse effect as many people started tuning into the show to see why she was boycotting it. Because of this, ratings actually soared and got more viewers.
Question: What did Al remove from The Lundys' car to cause it to crash?
Answer: It was one of the hoses connected to the engine, nothing specific, but to indicate that Al tampered with the vehicle.
